How to propagate and cultivate Chinese roses
The following is a detailed introduction for netizens on how to propagate and cultivate Chinese roses, as well as related content about the maintenance steps of Chinese roses. Let's follow the editor to see the specific details!
Chinese roses have strong adaptability and are widely distributed throughout China. They come in many varieties with rich flower shapes and colors. The blooming period is long, from August to April of the following year.
There are many methods for propagating Chinese roses, but the most commonly used is cutting. Depending on the location of the cuttings, they are divided into new bud cuttings, softwood cuttings, and hardwood cuttings. Let's learn about them together.
I. New Bud Cuttings
1. Cutting Time: The cutting time for new buds of Chinese roses is generally in spring, when the new buds have just emerged and have strong vitality, making it easier for them to root and sprout after cutting.
2. Cutting Selection: Choose strong and plump new buds, remove them and clean them thoroughly, then set them aside for later use. If the new buds are weak, the survival rate after cutting will be low, and even if they survive, it will affect subsequent growth.
3. Cutting Process: Use simple soil for Chinese rose cuttings, such as sand, vermiculite, or perlite. First, make a hole in the soil surface with a stick, then insert the new bud into the hole, about one-third deep, and press the surrounding soil to ensure the plant does not fall over.
4. Subsequent Maintenance: After cutting, water thoroughly and cover with a layer of plastic film to create a humid environment. Open the ventilation twice a day, and after 15 days, they can root. The film can be removed after 20 days, and they are ready to be transplanted.

II. Softwood Cuttings
1. Cutting Time: Softwood cuttings of Chinese roses are done in two periods, one in spring from April to May, and the other in autumn from September to October. These periods have warmer weather, which results in higher survival rates. High temperatures and humidity in summer can cause wounds to rot, making it impossible to root and sprout.
2. Cutting Selection: Choose strong, disease-free branches from the current year for softwood cuttings. After the flowering period, remove the flowers and old leaves to accumulate nutrients. When the branches are sturdy, they can be cut. The length of the cutting is 10 centimeters, retaining two compound leaves and small leaves, and removing the rest.
3. Cutting Process: Mix leaf mold and coarse sand to prepare potting soil. Dip the lower part of the cut branches in rooting powder, insert them into the potting soil, and leave about two-thirds deep, ensuring 2-3 buds are exposed.
4. Subsequent Maintenance: After cutting, water thoroughly and cover the potting soil well. If new buds appear and the old leaves do not fall off, it indicates that the cutting has been successful.
III. Hardwood Cuttings
1. Cutting Time: The cutting time for hardwood is at the intersection of winter and spring when the temperature is still relatively cold. Although the cuttings will not root immediately, there is a longer period of preparation.
2. Cutting Selection: Cut a strong hardwood branch, remove the lower leaves, and retain 2-3 leaves to prevent the leaves from rotting in the soil, causing bacteria to grow and affecting root development.
3. Cutting Maintenance: Insert the branch into the sand, water thoroughly, then set up a frame, cover with a layer of plastic film, and place it in a sunny spot to receive sunlight. When the temperature gradually rises, the film can be removed, and when the leaves turn green, it can be transplanted.
